Hello I got an extension which works fine on windows systems, but openoffice crushes when i try to use in on linux, tested it on Arch,CentOs,fedora results are same... There is no exception thrown in logs, also no exception happens when debugging from source code.What may be the reason?

Unfortunately can't link the extension.Its custom extension, it just loads javafx window to connect to other software, can see the addon in openoffice menu but when it tries to load javafx openoffice freezes. Is there any known issue with openoffice & javafx in linux?

No it's same when i run it in debug mode, the problem is that there is no exception thrown whatsoever, no errors in openoffice logs, but it freezes. Cant understand what causes the crush, os java or oo.

Managed to catch exception, it had problem with loading resources and class initialization. I think there is some problem which bugs classloader when javafx launched from oo. So, manualy setting classloader in init methods solved the problem.

I don't know enough about Java to comment sensibly, except to say that when a program/macro works in manual mode and not in installed mode, there can often be some form of timing problem. A delay loop inserted might cure the problem - there was a recent case of this reported on the Forum when a macro was being used.
